Wildlife: why do mosquitoes drink blood and why do they die?

Before I explain to you why mosquitoes drinkblood, I want to introduce you to the general course of affairs. Perhaps some of you, dear readers, still do not know, but not all mosquitoes suck blood. Some of them regale themselves with nectar (for example, males), others prefer to suck sap from plants, and there are also such species that do not feed at all (for example, long-legged peas)! Usually, these "herbivorous" mosquitoes gather outside the city into whole clusters of tens and even hundreds of thousands of individuals! They are jostling in one place, emitting a piercing ringing that attracts females ... The mating period is expected. But more about that some other time. Now we are interested in why mosquitoes drink blood, which means it will be about females. They are the real vampires! It is they who do not give us peace of mind, day or night!

So, only females bite humans and animals.mosquitoes. About males out of the question! The "bloody menu" is not caused by the whims of females, but a necessity!

That is why we are indifferent to them!

The fact is that our protein is a building protein.the material needed by the female for the production and normal development of her eggs. After all, plant food, as you know, is not rich in proteins. From the full-fledged consumption by the female of the mosquito of this "building material", the whole cycle of laying its eggs is directly dependent. The more protein a mosquito consumes, the better its clutch will be. That is why the female can suck blood much more than its own weight (if it is, of course, not slammed).

Of course, you do not need to think that the only thingAn explanation of why mosquitoes drink blood lies in their ability to reproduce. The eggs will be laid by the female anyway, but if she doesn’t pump the right amount of blood, the heroine will die: give the eggs their own proteins at the cost of their lives. However, if the blood in terms of the source of food will be completely inaccessible to mosquitoes, they will simply die out!

Scientists have found that mosquitoes do not just pierce the skin with their sharp proboscis, injecting a special liquid into the blood that prevents it from clotting, but fully control it, looking for capillaries. Only after the desired capillary is found, does the mosquito inject its saliva into it, which rather technically prevents our blood from clotting and then begins to suck. By the way, this is why a mosquito bite severely itches - the liquid causes irritation.
